I found the comment on Activity#onConfigurationChanged method.
If I do not set the activity element's configChanged attribute, then
the System will restart my activity.
But again, how should I override this method, just add a empty method
body there?
Thanks.
/**
* Called by the system when the device configuration changes
while your
* activity is running. Note that this will <em>only</em> be
called if
* you have selected configurations you would like to handle with
the
* {...@link android.R.attr#configChanges} attribute in your
manifest. If
* any configuration change occurs that is not selected to be
reported
* by that attribute, then instead of reporting it the system will
stop
* and restart the activity (to have it launched with the new
* configuration).
*
* <p>At the time that this function has been called, your
Resources
* object will have been updated to return resource values
matching the
* new configuration.
*
* @param newConfig The new device configuration.
